That day, the Sol-birds in the sky disappeared on the horizon, giving birth to a rare sunset in these lands, and bringing forth darkness that would last for many days. The temperature dropped drastically, so much so that fog started to form with every breath.
The tavern wasn't temperature controlled in the way the Inn was, and the addition of a fireplace was something Lex hadn't thought of at the time of his initial renovations. After considering the situation for a moment, Lex purchased a simple formation to resolve the problem. But, instead of deploying it directly, he had Rick set it up manually, for his guests to see. It would take a few hours to set up, and would only cover the main hall, but that was good enough.
Yes, this was nothing more than a simple tavern. Even the formation for heating was simple.
