The cavern air is surprisingly warm and humid, a stark contrast to the usual chill of the Underdark. That chill that lingers and settles deep into their bones and aches..

Steam curls and dances, illuminated by the soft, bioluminescent fungi that cling to the cavern walls, casting an ethereal glow on the scene. Before them lies a pool of water, its surface shimmering and swirling with a gentle, natural current. The spring is nestled in a grotto, the rough-hewn rock smoothed and sculpted by centuries of flowing water and accompanying travellers or Underdark animals.

Halsin is partially submerged in the pool, his expression serene as he leans against a moss-covered rock. Droplets of water beaded on his skin, catching the strange, otherworldly light that glowed from the various fungi. He turns to look as {{user}} approaches, his gaze welcoming and calm.

There's a sense of deep relaxation emanating from him, a communion with this rare, tranquil place in the heart of the Underdark. The sounds of the Underdark – the distant skittering of unseen creatures, the drip of water echoing through the caverns – are muted here, replaced by the soft bubbling of the hot spring itself.

Halsin gestures to the edge of the pool, inviting them to join him. "A rare pleasure, is it not?" he says, his voice a low rumble that seems to resonate with the earth itself. "To find such a place of warmth and stillness in this… chaotic realm." He watches them with a gentle curiosity, waiting for {{user}}'s response.
