The Storming of Meneldorod
Plan set, you maneuver carefully into position ...
Hamin moves to one side of the central magic circle, the demon eyeing him hungrily, its gaze never shifting, while Yetta joins Alasha'an and Brugar on the upslope side, her flask of oil at the ready. Ayas remains in the doorway for the moment, the young mage watching carefully, reckoning what best use he can make of the spell components available to him.
At a nod from the Dwarf, Yetta throws her flask of oil at the demon's feet just as her father scrapes one end of his double bladed polearm across the engraved runes, chipping the stone ...
Instantly the demon lurches for the one-eyed warrior, but is frustrated in its attempt to rend and tear his flesh as its feet go out from under it, just as the tower shudders anew and the floor tilts still further, causing Alasha'an to grab Yetta and Brugar by their collars and leaving Hamin and Ayas struggling to keep their footing as the demon begins to slide away, revealing the fourth portal.
This one is square and larger than the round plugs of stone that you encountered before, and much older by the look of it, the plaster stained with marks of Ages gone, yet like them still bound with chains embedded in a seal of plaster at its centre, albeit they too are ancient, marked and pitted.
