The Dilgar were an aggressive feline-like humanoid species. They attempted to expand their territory by invading those sectors of space held by The League of Non Aligned Worlds between 2230 and 2232 As the Dilgar War broke out the Earth Alliance fought on the side of the League and battled the Dilgar forcing them back to their homeworld. After the war ended, the Dilgar sun went supernova, effectively wiping out the entire species. Only Deathwalker survived having fled the Non Aligned sectors and been sheltered by the Wind Swords clan of the Minbari Warrior caste. She was eventually killed by the Vorlons in 2258, making the Dilgar finally extinct.
