Hoeth

Hoeth, Lord of Wisdom was the Elf/Eldar god of progress, curiosity, and paperwork. Most of the knowledge known by the good races (reading, writing, gravity, how to sail, and so forth) was granted by Hoeth directly. There's two versions of WHY Hoeth did this. The first, because that's a good thing and he's a nice guy. The second, because knowledge is the stuff of LIBERALS and thus the enemy of conservatives and religious nutcases. To support the second theory is the fact that Asuryan, god of among other things tradition and the right to rule because nobody has ever questioned why he's allowed to rule, torched Hoeth's entire personal library as revenge for it. But since Hoeth had invented magic computers by this point he gave no fucks.

Wizards and scientists presumably have a great deal of respect for him, and the capital of Saphery as well as the giant fucking tower there (which is the location of the center of magical internet and magical television) is named after him.

The High Elves are all crazy over him and he is one of their major gods. The wood elves are not shown to honour him but since he is a god of knowledge and wisdom it is entirely plausible some do. The Dark Elves hate all the Cadai gods so therefore they must had knowledge and learning too....suck it up you fools, you are the ones that made that rule in the first place.

Warhammer 40,000

Nothing is known about the Warhammer 40,000 version of Hoeth (or if he existed). Presumably, he was identical to his 40k version until he was raped in every orifice and eaten by Slaanesh. Tzeentch may have had interest in him, but anything but Slaanesh's involvement is pure fanfiction.
