The bottom of the pool was probably much, much more shallow than the hot springs in the Blooming Grove. But depth was a difficult thing to judge and while space was iffy and unburdened by the laws of physics within the Tower, there had to be a bottom somewhere. Caleb couldn't touch the bottom, but he didn't know if Caduceus would be able to. He had at least a foot on Caleb, maybe a little more than that. But the stones within the pool were arranged in such a way that they created descending tiers, so there were plenty of footholds and places to rest within it.
He dipped down into the water as well, submerging beneath the surface enough to get his hair good and wet. He could feel the heat rolling along the scars on his arms and when he surfaced again, soft tendrils of steam rose off the intricate sigils. He navigated carefully towards Caduceus and folded his arms over one of the stones, resting his chin on top of them.
"That's probably a good rule to have," he said, the heat already soothing some of the tension out of him. "But since the ecosystem here is all in my head, it's probably fine." The only thing he'd really worry about was the cats and they were all fey and, again, mostly imaginary. They would be fine with whatever happened.
He chuckled softly and lowered his face into the hollow between his arms for a moment. "Jester spent the first month we were together calling me a stinky wizard so," he shrugged and looked back over at Caduceus. "I think there's only room for improvement. And if you like it, that's good enough for me." He didn't realize the implications of what he said. Caduceus probably didn't either. That was for the better, really, because Caleb would have been embarrassed otherwise. "I leave it all to your judgment. So far you haven't steered me wrong."
