| In the grim darkness of the far future, the T'au'va burns bright.
|-
|Thematically, the T'au sept demonstrates the T'au beliefs to the fullest. From the political ideals of T'au to their tactics, the T'au sept is the singular source for everything regarded as properly T'au. Having a great concentration on Ranged warfare and ways to make sure things keep far away, they are the building block of which every other sept in the T'au Empire is built, and have spawned many great heroes over the course of hundreds of years.
|-
|On the tabletop, they lean heavily into their HQ support, with the best and most numerous special characters and all of their HQs able to support more at once from farther away, with the rest of the army being as MSU as possible.

;Tenet - Coordinated Fire Arcs: Each time a unit is selected to shoot or fight, it can re-roll one hit roll or one wound roll. Add 3" to the range of aura abilities of this model - to a maximum of 12". When this unit uses a command phase ability with a set range, increase its range by 3" - to a maximum of 12".
:*It's always better to re-roll a hit roll than a wound roll for the same gun when you're forced to choose - you should only use the re-roll wounds ability when all of a unit's attacks hit or when a unit has mixed guns (it's better for a Hammerhead that hits with its railgun to hold onto this ability to re-roll to wound than to spend the re-roll on a burst cannon shot).  It's better on units that make fewer shots at worse accuracy - it's more accurate than re-rolling all 1s to hit if you make 5 attacks or less, and it's more accurate than +1 to hit if you make 2 attacks or less on 4+ or better or only 1 attack on 5+.  Likewise, it's better on weaker guns than stronger guns, and since it doesn't help you penetrate or deal more damage, it's better on guns that do both well; its ideal gun for your army would be if you could legally field Pathfinders with Rail Rifles on their own, without the accompanying unit.  In practice, your best unit for this trait is MSU Broadsides.
:**On a Hammerhead's railgun, assuming you're BS3+ from a markerlight and you're shooting a T8 target, this takes you from a 44% chance to hit and wound to a 74% chance (after rounding); the net benefit is 67%, i.e. 2/3 again as powerful.  By contrast, a full unit of 3 Broadsides unloading their railguns into the same target (so same base accuracy and chance to wound) go from 2.67 times successfully wounding to 3.13 (after rounding), a net benefit of only 17% - the Broadsides get less benefit due to their much higher rate of fire.  Against a T5-7 target (so the Hammerhead hits harder base), the Broadsides are the same, but the Hammerhead goes from 56% hit-and-wound to 83%, a total benefit of 50%, because the more easily you wound, the less this ability helps you.
;Warlord Trait - Strength of Conviction: 5+++.
;Relic - Vectored Maneuvering Thrusters: {{W40Kkeyword|Battlesuit}} only. Add 2" to the bearer's movement. Once per round, when the bearer is selected as a charge target, if it is not engaged, it can make a normal move. If it does, until the end of the phase it cannot fire overwatch or set to defend, and your opponent can select new targets for the charge.
;Stratagem - Focused Fire (2CP,Battle Tactic): Use in your shooting phase, when a model in an enemy unit loses wounds due to an attack made by a {{W40Kkeyword|T'AU SEPT}} model. Until the end of the phase, {{W40Kkeyword|T'AU SEPT CORE}} models in your army gain +1 to wound against that enemy unit.

=====Units=====
Note that two of your characters can be taken by any Sept, so they've been moved out to the general unit discussion.  All of the units below are HQs.

*'''[[El'Myamoto_(Sub-commander_Darkstrider)|Darkstrider]]''': For his statline, he's a Fireblade with +1Ld, +1W, +1M, and -1WS/BS (i.e. he's more accurate).  Equipment-wise, he has his own Fireblade version of a Pulse Carbine he insists on calling "Shade" because he's even more weeb than a normal weeb; it's literally just a 24" Assault Fireblade Pulse Rifle.  He also has a normal markerlight and no drones at all.  For his abilities, he's kept his old Pathfinder ones, so he has 7" Scout move and can take the Markerlights action at the end of the Move phase instead of the beginning.  His remaining abilities are bespoke.  His compulsory WT is the one for autoadvancing 6" and being at -1 to be hit.
**'''Structural Analyser''': In your command phase, pick a friendly {{W40Kkeyword|TAU SEPT CORE}} unit within 6” and one visible enemy unit. Until end of turn, models in that friendly unit get +1 to wound with ranged attacks against the enemy unit.
***Doesn't specify {{W40Kkeyword|CORE}} ''models'', so this works on Drones in a Core unit just fine.  
***Since he doesn't only target core models in the core unit, this will buff Drone guns just fine - and he has his own markerlight, lightening the pressure to take marker drone spam.  Just make sure someone nearby has a Drone Controller if you're going to try this.
**'''Drone Familiar Cluster''': Each time this model shoots, re-roll one hit roll and one wound roll.
***That will stack with the Sept Tenet, giving him 1 hit roll re-roll, 1 wound roll re-roll, and 1 floating re-roll he can spend on either when he shoots.  
**'''Fighting Retreat<sup>Aura</sup>''': Friendly non-{{W40Kkeyword|battlesuit}} {{W40Kkeyword|TAU SEPT CORE}} units within 6” can shoot after falling back.
* '''Longstrike:''' No longer an upgrade to a Hammerhead, but a separate HQ unit choice and {{W40kKeyword|CHARACTER}}. Gains additional BS (down to 3+ base) and some abilities - otherwise he's a Hammerhead in all respects.  You can make him your Warlord - his compulsory WT is the targeted buff where 6s to hit autowound - but you shouldn't; his real job is being an extra Hammerhead that's extra good at murder and occupies an HQ slot instead of a heavy slot.
**'''Gunship Ace''': Longstrike’s ranged attacks against {{W40Kkeyword|MONSTER}}/{{W40Kkeyword|VEHICLE}} units have +1 to wound.
**'''Targeting Array''': Each time this model shoots, re-roll one hit roll.
**'''XV02 Pilot Battlesuit''': In your command phase, select one other friendly {{W40Kkeyword|TAU SEPT CORE}} or {{W40Kkeyword|tau sept HAMMERHEAD}} unit within 6”. Until the start of your next command phase, when that unit makes a ranged attack, it treats the target as having a markerlight.
