Are you sure that Hephaestus lighting the forge is a necessary part of every session? I thought that in the particular case of the beta kids' session thay needed it to melt the snow on LOFAF, but space players' lands aren't always frozen, are they?

Hephaestus doesn’t light it, my mistake, the Space player does.  But it always needs to be lite.  It melted the snow in Jade’s land and dried up the water in Kanaya’s.
