The Grey Council

At the beginning of your upkeep, if you control 3 Legendary Minbari Warriors, 3 Legendary Minabri Clerics and 3 Legendary Minbari Workers, you win the game.
"If the council has lost its way, if it will not
lead, if we have abadoned our covenant with
Valen...then the Council should be broken, as
was prophesised." — Delenn
