The following section contains information from StarCraft: Insurrection.

Carpenter's Brood used several to coordinate their final defense against the Zerg Swarm. The Brood was defeated, however.[1]

Twilight StruggleEdit

In Twilight Struggle, each cerebrate is attended by an Yggdrasill.[2]


The Yggdrasill is the basic zerg hero overlord in StarEdit.
