Heskal

"Please defend yourselves."

- Tersu

Heskal was a Human Male from the planet Zakuul who was the leader of the Scions of Zakuul, a subgroup of the Knights of Zakuul that specialized in Force visions and were obsessed with the idea of fate. After Emperor Arcann ordered the massacre of the Scions around the time of his ascension to the throne of the Eternal Empire, Heskal was among the few Scions who escaped the purge and settled in an enclave on the shadowport Asylum still under leardership. Around 3635 BBY, Heskal summoned the figure known as the Outlander and to Asylum and tested the foreigner to determine why they could not see the Outlander's future. Along with his Scions, Heskal attacked the Outlander with Maral in one of a series of combat tests that ultimately revealed the presence of Valkorion, the Immortal Emperor, within the Outlander's mind. The Scions promised their loyalty to the Outlander, but Heskal later betrayed the Scions and the Outlander to Arcann and drew him to Asylum, as his visions led him to believe it was necessary to force a confrontation. Arcann killed Heskal's followers and wounded him just before the Outlander's arrival, sparking the Battle of Asylum. During the battle, the wounded Heskal was drag away from the battle by the Knights but his escort party was beaten by the Outlander. Heskal died soon aftermath.
