What took you so long? (The Final Trial)

Our heroes accepted a request at the Inn and found themselves teleported to a different realm one with a rather large arena they heard chatter outside of what elements may be involved, but soon they found out for themselves facing the first element snow, they fight mammoths and frost giants, slaying them with ease, moving on to the next element water where they had a little bit of a harder time, one member dying and getting consumed by a shark, but another member was able to bring them back to life just in time and they were able to slay the shark and break free, another was eaten by a sea serpent, but he grew angry and literally exploded from it's stomach killing the beast instantly, they went to the forest area and quickly dealt with the treant there that was causing a ruckus, next were the final challenge in which they had to discern which shadow was real and they manged to do so after a short time and slay the real one.
