High Gish'ra Zelrin is a githyanki character encountered at the Wyrm's Crossing campsite at the end of Act Two.
Zelrin, alongside his fellow githyanki
Ghik'lir,
Hr'ack'la,
Jyd'i',
K'i'lar, and
Nyk are members of
Orpheus' honour guard. As the guard attempts to free Orpheus and escape the Astral Prism, they clash with the party during their first long rest outside the Shadow-Cursed Lands, at the end of Act Two on the road to Baldur's Gate.
Zelrin is part of the second wave of githyanki that spawns from the portal.
