Caele, is an acquaintance of Rohen Tahir and friend of Tahira.
Before the Convocation
While the exact time isn't known, Caele, together with Joshua and (most likely) Lev was part of a group hunting the giant named Lordir (originally "Lördir"), lead by a Dwarf named Skjalf.
These events are depicted in the short story Guardian in the Mountain.
Battle for Fiara
She was a member of a group tasked by Rohen with retrieving a special rune from the ruins of Ankbrand which was in possession of an Orc chieftain named Krong. The group was ambushed by the Orcs and forced to abandon the mission, deciding instead to seek out their friend and Rune Warrior Tahira who lives nearby.
Together with Lev, she fought her way to Tahira's hut in the North of the island - when Lev got injured, she hastened on her own, eventually reaching her friend's hut. Though the Rune Warrior was reluctant at first, Caele managed to convince her to assist them in their mission.
Her current whereabouts are unknown.
