If before, then there would be no sun (and honestly, I don't see any reason why people without at least low-light vision would even exist on such a planet).
The home game canon is that the planet was born in a sort of nebula that glowed brightly enough to support life. The place was sort of a garden/Limbo, where the rules of reality were in flux, and invaders wanted to plunder resources. Toteth was an admirer of darkness, and wanted it to crop up more often, and as they'd explored the multiverse he and his allies had seen worlds with suns, so instead of recreating the nebula thing when they did the Axis Seal, they created a system with a sun.
You got planets, and there were elemental spirits from Jiese, Avilona, Mavisha, and Urim manifesting in the Waking world. The dragon Jiese nearly killed the eagle Avilona, then hid the heart.
Civilization was in the Stone Age, and Lanjyr was particularly chaotic, since most of the invaders had been there. In 1200 BOV Kelland subdues the fey titans.
Around that time across the sea, folks have reached Bronze Age technology (Honestly, I wanted WotBS to be more Mesopotamia-inspired, but I didn't push that for the AP). The Torch gets created around 1120 BOV, and its powerful planar magic lets extraplanar creatures who are summoned around it stick around despite the Axis Seal. Some of them head west and start conquering the areas that are now northern Lanjyr. Then around 1000 BOV, we have WotBS, which ends with Leska and the Torch get buried at the Heart of History under tons of rocks. They're both technically still around, waiting for someone to dig them out.
About 500 years later (500 BOV), tech level advances to early Iron Age. Triegenes thwomps the Demonocracy. Meanwhile, who knows what's going on over to the east.
Tech level advances to roughly high Middle Ages (algebra, chemistry, large cathedrals). The two Victories happen, and then the Great Malice (1 AOV). Meanwhile, who knows what's going on over to the east.
Tech level advances to early-Renaissance in most of Lanjyr (300 AOV). In Danor, active research into technology and industry is promoted so the nation can compete against other nations with magic. By 400 AOV Danor has early steam-assisted ships, and by 460 it has full-on steam frigates. By 500 Danor and Risur both have armored steam warships.
