Impact
They walked their way up the Staircase, to find their selves glaring upon a portal carrying a purple like colour, spanning 6 meters horizontally across the ground! If finding a portal here deep in the mountainside isn't interesting enough, its true colour is overwhelmed by the purple light the Ignite Gems are providing above their heads!
Yes the ceiling of this room is filled with them, perhaps it is what the Snow Ignites where after? One Ignite Gem can be sold for 100 Gold Coins, this place was made before the 100 year long war and its terrible 100 year aftermath, so trading wasn't neccesarily hard. The prices a few centuries ago perhaps were smaller but it still met the economy standards at that time.
Another sign that this specific room isn't modified, is the fact that there are no fancy over the top carvings. There is just rock and dirt around, nothing fancy about it. It portrays a normal cave. There are two possible options of what happened up here!
