If a hero uses a glyph to return to town, can he/she return to ANY activated glyph or just the one they left from?
The reason I ask is that (And here's the spoiler alert) one of the scenarios from the Well of Darkness has the heroes separated by rune locked doors. The idea, apparently, is for them to work separately to gain the runes so they can re-group to finish the dungeon. But they all start next to a glyph. What's to stop them from all going to town then all coming back to the same glyph? Kind of defeats the spirit of the scenario....
From the FAQ:
Quest 2: Spider’s Web
Heroes may only use glyphs that they themselves have activated until the glyph in Area 4 is activated.
So in other words, yes, you may go back to any glyph, not just the one by which you entered town (this rule is important for surviving quest 1 in fact). There just happens to be an exception to that rule in this particular quest.
