Notes
Kelanen's crusaders are closer to fighters than to priests, but lay claim to modest spellcasting abilities (up to 4th level spells)
Kelanen has a significant temple on Jetsom Isle
The sword lore proficiency is similar to ancient history (and uses the same ratings). It consists of knowledge of famous swords, weaponsmiths, and swordsmen, both ancient and contemporary. As a hero-deity, Kelanen's crusaders are based on 80 points, rather than the standard 120
Background
Kelanen's origins are cloaked in mystery -- it is nearly certain that he was once mortal, and ascended to the divine by right of his sublime mastery of the blade. Oeridian records hint that Kelanen was once a soldier and armsmaster during the great eastward migration. The Flan also lay claim to him, as a champion against the Oerdian influx. What is certain is that Kelanen fought on both sides of the Flan/Oeridian struggle, and was instrumental in forging a lasting peace in what is now Nyrond. Kelanen then departed from the pages of history -- but not from the affairs of man.

Divine matters now occupy most of Kelanen's attention, though he occasionally sallies forth from his stronghold to train promising mortals and to strike blows for the cause of Balance. He is allied with many of the active powers of Neutrality, including Rexfelis, Mordenkainen, Basiliv, and the Mad Archmage.

Kelanen has many worshippers (nearly all who live by the blade pray to him on occasion), but few true priests. His most dedicated worshippers gather in small shrines or monasteries, honing their skills towards unknown ends. These monasteries each have a handful of true crusaders of Kelanen, with the majority of the acolytes being normal fighters.
