The elderly high elves convene next to a ring of mushrooms and frantically discuss the situation amongst themselves. After some convoluted arguments, they assemble strange silver equipment and commence a series of experimental attempts to construct magical portal. This takes a while. It's hard to track the passage of time here. Maybe an hour. Maybe more. They implore you to wait, that it won't be long before they arrive at a satisfactory result. After several brief flickers of light from a collapsing and unstable portal, a few minor explosions, and a spontaneous shower of phosphorescent blue globules, they manage to create a seemingly stable portal.
A massive pink tentacle reaches out of the portal and grabs one of the high elves. Ty and Dorgath act quickly, grabbing the old man before the tentacle can drag him into the portal. All three are slowly pulled toward it. Kelgar grabs his comrades and slows the tentacle down even more, but it is extremely strong. Throg laughs at them. Jekaena struggles to maintain the spell keeping the party from losing themselves in the beauty of the Idyllic Copse, but by now she is faltering. Dorgath, Ty, and Kelgar manage to mostly focus on resisting the pull of the tentacle, but they're becoming increasingly distracted by how aesthetically pleasing the trees and flowers are. Revaethan steels himself and plunges both of his swords into the tentacle. Tomas casually strolls over to the tentacle, conjures a thick hammer of flame, and bashes the tentacle repeatedly. Despite their efforts, the party is gradually losing the tug-of-war. In a heroic surge of strength, Kelgar heaves backward. The tentacle stretches out for a split second, and that's all it takes for Revaethan to hack through it. The lower half of the tentacle retreats back into the portal, then the high elves instantly deactivate the device. The Honored Elder that the party rescued is shaken, but generally unharmed.
The high elves bicker some more over whose fault that last mishap was. This goes on for a while. Jekaena's magic continues to wane. After they settle down, they open a new stable portal, one without any tentacles. It's not quite leading to the right location, but they leave it open an analyze it, performing some calculations. While they have the portal open, a floating inky-black shadow in the shape of a weasel drifts toward the portal and enters it. The party cannot help finding this amusing, but the Honored Elders shut down their portal again, and descend into panic and argument.
While the escape of that shadow-weasel creature distresses them, the Honored Elders are still resolved to help the party leave, and they're now confident that they can create a portal to take the party back to where they were before, in the Enchanted Wood of the Heart-Tree of Welhallas. They only dare risk leaving the portal open long enough for the party to enter. Then they'll close it so nothing else from the Idyllic Copse gets out. So they advise you to get ready...
The portal, once opened, should be wide enough for you to enter two-at-a-time. In what marching order will the party proceed through the portal?
