Trayzeal lets his arrow fly, but it sails over the head of the weird creature in lands in a lake in a large cavern. Trayzeal is able to glimpse a body of water leading off into the eastern shadows with rowboats at the edge of the lapping water. A door stands to the north and another passage leads off to the west. He also sees three more of these creatures. No-one else can see anything as it is too dark. But the battle is on. The creatures move into attack. Orvex throws a fireball into the chamber which creates light, especially after the rowboats catch alight. b'Urp enhances the flames and hangs from the top of the cavern when not throwing punches and kicks and you all manage to defeat the foes. However you fail to notice that only 3 corpses are lying in front of you. The fourth had left down the east passage to get help, and as you are starting to explore the main chamber you are suddenly rushed by more of the creatures. Thazma is wounded and throws up a wall of force to protect herself and Besh. But Orvex gets rushed by two of the creatures. He throws a thunderwave at them which throws them back, but a loud boom echoes throughout the complex. There is no longer any chance of stealth. b'Urp also spots a Yuan-Ti peeking around the corner of the western tunnel. When it is seen it ducks back and disappears. You eventually defeat the second wave of creatures and start re-exploring the chamber, with a couple of you scouting the western tunnel to see where it goes. But is the main chamber a hydra bursts out of the water and rushes at b'Urp. It had been some distance away in the water, but the sound of the thunderwave had attracted it. b'Urp is badly hurt and manages to squeeze back to the southern tunnel where Besh is standing, but the rest of you flee into the western tunnel. You attempt to fight the creature and cause it some damage, but it is a dangerous and difficult foe. Both tunnels are too narrow for the hydra to enter. The party is now split with b'Urp and Besh in the entrance tunnel and everyone else in the western tunnel.  Thazma turns invisible and makes her way to the southern tunnel. "Come with me, you fools", she says to Besh and b'Urp as she squeezes past, "Your friends are dead already. These foes are beyond your ability. Come back to the city and we will formulate a plan rather than your approach of bumbling into disaster With that, you feel the air move as she passes and she is gone. Meanwhile, the rest of you make your way into a another chamber where 3 naked chultans look at you with blank eyes and expressionless faces. You briefly attempt to communicate with them but get nothing. Trayzeal uses his thieves tools to pick the lock of the door to the north and reveals a storeroom. Stacks of sturdy wood crates, bundles of cloth, and clay amphorae litter the floor. However Trayzeal's keen eyes note a giant snake hiding amongst the items. Grizz Lee summons a pack of velociraptors who quickly tear the snake to shreds. However as this happens yuan-ti and broodguard appear at the junction to the north and start swarming down the passageway towards you. Orvex casts confusion which stops two of the yuan-ti, blocking the ones behind, but some of the yuan-ti and broodguard are able to make it into the room, attacking you but getting attacked by the velociraptors. You look up the passage and see more of the enemy heading across the passageway towards the east. You are getting worn down and you cannot see an end to the enemy. Suddenly you see a figure appear at the end of the passageway who calls out to you. "I am Fenthaza, dream speaker to Ras Nsi. We invited you here in peace to talk, but you sneak in like thieves and kill our people. You will die if you do not surrender now" You answer her with spells and arrows so she steps back out of sight. "So be it", you hear her say, "we will defeat you, and those that survive will wish they hadn't". Meanwhile back with b'urp and Besh, they are wondering how they will get past the hydra when they hear a hissed command. The hydra immediately backs away and returns to the water. Then a yuan-ti steps around the corner with a strange beast. It is a basilisk. It stares at b'Urp and he feels his body start to stiffen. "Run Besh", are his last words before he turns to stone. Alone and with no hope of defeating this creature, Besh flees back into the city of Omu. Meanwhile the rest of you are fighting the creatures that pour down the passage, building a mound of corpses. You see a basilisk also, but the velociraptors are able to defeat it before anyone is affected by it's gaze. Orvex decides that he has had enough and flees back the way you entered from only to find more yuan-ti approaching from that direction. The enemy have you in a pincer movement. Orvex returns and warns you all. "Stand back", says Grizz Lee and starts chanting in a voice that sounds like grinding stone. The stone of the walls begins to morph and Grizz Lee forms it across the passage back to the entrance, blocking it completely. You are now safe from the enemy at your back but the enemies from the north keep on coming. You have cut off your escape and you are running short on resource. Realising your imminent defeat, Orvex begins taking his clothes off so that he can pretend to be one of the slaves, but as he does so Shmesh is suddenly enchanted by a yuan-ti and begins attacking him. Orvex casts a charm spell in response which seems to counteract the suggestion, but the enemies continue flooding in and the situation seems hopeless...
