In StarCraft II, what is the name of the Protoss arkship that carries survivors of Aiur?

In StarCraft II, the Protoss arkship that carries survivors of Aiur is the Spear of Adun.

The Spear of Adun is a massive Protoss arkship and the central setting for much of Legacy of the Void. It was built to preserve Protoss life and technology during the long period when the Protoss expected Aiur to fall.

Artanis uses the vessel as a mobile command center while attempting to reunite the Protoss and reclaim their homeworld. The ship also contains advanced systems and an ancient AI known as the Khala, although the campaign explores the political and spiritual consequences of Protoss reliance on that network.

The Spear of Adun is often confused with the Hyperion, which is Jim Raynor’s Terran battlecruiser and the campaign hub in Wings of Liberty. The Gantrithor, meanwhile, is associated with Tassadar in the original StarCraft.
