Caranthalis is a god associated with the tree of light and blessed branches, known as the Tree of Light. The deity is one of eight gods, focusing specifically on the Sacred Tree under the protection of a Guardian beast. Ygva seeks remnants and totems of Caranthalis to draw the deity into the World Below, aiming to bind the gods with titans to prevent the upper world's ruin. She states that there are eight altars dedicated to the gods, including Caranthalis, and intends to balance the offerings before attempting a significant summoning. Various artifacts associated with Caranthalis, including a book of pressed flowers, are gathered as part of Ygva's goal to amass god-touched items for the ritual.
The party confronted the Guardian beast tethered to the Sacred Tree. After a series of violent encounters, the beast was killed, revealing a collar that suggested a connection to the tree. The Sacred Tree was burned and regrown, lacking vitality. The party recovered blessed branches from the tree, which contained fleeting divine power.
Heyou played a significant role in investigating the fallen beast, using his daggers to sever its head. The head revealed gray viscous fluid instead of blood, indicating the creature's supernatural biology. The party successfully gathered three substantial blessed branches and discovered seed-like objects around the tree, identified as potential means to grow new sacred trees.
Following a catastrophic explosion caused by goblins mishandling explosives, the party faced dire consequences and initiated a hasty retreat. They encountered Kelun, who blocked their escape and demanded they follow him to face Ygva, emphasizing the weight of divine judgment in the aftermath of their destructive actions.
