Is there a dwarven deity for whom the Light domain would be applicable? Obviously, with GM buy-in you can take any domain for any deity, but I'd prefer to create a thematically consistent character. I've been looking around, but the dwarves don't appear to have a sun god, or a fire god, or any of the usual suspects for Light domain clerics.
The setting is Forgotten Realms, and the game is D&D 5e. Since the only dwarven deity in a 5e book is Moradin, I'm open to anything from an earlier edition. Just including 5e on the question to avoid any gods who have been killed or otherwise removed from canon.
Also worth noting that while I'm open to answers like 'Moradin works for the Light domain because such-and-such', it's easy to see that Lathander (or, preferably, the dwarf version of him) is far more thematically appropriate.
