Then by posting here, you're just wasting forum space. Saying "I can't help" isn't a valuable contribution to this thread.

Thanks.
Defeating Tiamat does NOT light the orb! After beating her, you must walk forward and step on the altar to light the orb (this is not the same as the space that warps you out, but is before that space). If you cast WARP or EXIT before you did that, then you didn't light the orb.
Let me know if this helps.
