Green Pass Campaign IV, Session 3: Undermined

October 29, Caudex Annales, 70 AUP
The party ascended to the stairs to discover that the chapel had become a cathedral of horrors. Evil signs and markings covered the walls and floor, and all things of beauty had been vandalized or ruined. The old altar was broken, and instead there were five rough hewn stones of some necromantic origin, all of them pumping up various foul energies to the ceiling. Four of them were surrounded by undead: 3 soul-draining spectres, 6 armored black skeletons, 24 orange-eyed funeral pyre zombies, and 4 of the nine-skeleton polearm phalanxes, with each group distributed to a different corner. The center of the room just below the green sky-beam was shrouded by magically-animated fumes and debris, but clearly someone was chanting near the center. The ceiling above had been shattered where the beam had torn a huge hole.

Nothing in the room seemed interested in attacking, with only some slight defensive repositioning to protect the various evil altars. From outside the chapel, a mocking voice announced a challenge to come forth and meet the new rulers of Centerpost.

Instead, the mage Qaldor flew to the vestible and wizard locked the doors. The the party carefully arranged themselves around the apse and waited for the underground team of slimes and oozes to finish tunneling a level below.

Whack-a-mole on hard mode

On the ready mark, the party unloaded a volley of powerful magics at the spectres and zombies. The slimes then collapsed the floor below the enchanted stones, sinking them by ten feet into the floor (taking along the unfortunate prelate in the center). The horde outside banged on the doors while the party slowly mopped up the survivors, summoning in an earth elemental to smash apart any of the ritual stones that the oozes found indigestible.

At this point, April Dawnbow, who was watching out the window from the rafters, announced an incoming wave of gargoyle bogies (margoyles, actually) led by a balrog and another vrock. The squadron smashed through the large stained windows just as the party was retreating back into the tunnels, with Sir Pal, his pet bear, and the hydra covering their evacuation.

The hydra and balrog savaged one another as the vrock and gargoyles beat down the bear and began to surround Sir Pal. Meanwhile, the ooze patrol began to gnaw apart the foundations of four pillars in the center of the chapel which everyone agreed looked plausibly load-bearing.

After a couple rounds of getting clawed by dozens of gargoyle arms, Sir Pal announced a fighting withdrawal, and jumped into the central hole (with the vrock in hot pursuit). At that moment, the ceiling came down on the rest of the margoyle swarms.

Having eliminated one Ominous Sky Beam (tm), the party continued boring east across the city toward the second, while the previously frustrated occupiers above erupted in an unexpected wave of celebration...
