Editing Io (section)

===Pre-4e===
Io was introduced in the 2e Council of Wyrms adventure module as the Chief deity of the dragon pantheon and the father of [[Tiamat]] and [[Bahamut]]. He's also described in the Dragon section of the 2e Monster Mythology splatbook. This entry not only describes him as having all Alignments present in him simultaneously, but also makes him sound like <i>the single most fucking powerful entity in the entire D&D Metasetting.</i> Of note is the fact that as opposed to how things are in 4e, Io remains quite alive and healthy, having fathered Tiamat and Bahamut in the more conventional way (who their mother is, if there is one, is not stated).
