I have a lathanderite paladin.
He loves lathander and believes he does his lords work by aiding the grand endeavour that is the Silver Marches and to protect the good folk trying to make their own new beginnings in this dangerous, savage, new frontier by driving evil away from them. He also likes jogging

He is also devout to Torm. His father was a Tormtar paladin and the lessons and example of duty have rubbed off on my PC. He has his own code of behaviour (eg torm) while undertaking his work for lathander believing that this mission is, in part, a duty (eg torm) as well as a 'life-quest'.
He wears armour with both dieties symbols embossed upon it as part of his homage, but the blessed symbol on a necklace over his heart is that of the rising sun.
OOC:
Lathander's his primary deity, Torm is the 'god of paladins'. So he workshops them both but to a different degree - lathander first and foremost
In a pantheatic world such as FR, folk would pray to many gods. A farmer who is part of a militia may pray to Tempus before repelling a raid on his village, chauntea when he returns to his crops, waukeen when bartering at the market and even Talos when the storms look like destroying his harvest etc
But for a paladin the rules must be tighter and I'd appreciate you opinion on the above.
