The Alysaar ("Keepers of Wisdom") are a group of Dark Templar who reside in the Alys'aril on the moon of Ehlna. They record and store the memories of Dark Templar in khaydarin crystals. Known for their strong discipline and unwillingness to change the way they do things, they spend much of their time moving memories from damaged or time-worn crystals to fresher ones. The alysaar are led by the protoss with the title alysaar'vah, a term similar in meaning to "head librarian". By 2503 the Alysaar'vah was Krythkal.
