This is the first room of my new dungeon.

A couple of farm kids accidentally excavated an entrance to an ancient burial mound deep within the ground. It is perfect for adventurers who want to make a name for themselves exploring the tunnel and beyond.
The tunnel is long and unlit. The walls are mostly made of packed earth and stone with the occasional very old wooden brace. Those familiar with the earth may make a check to notice the grade of the floor. The long tunnel goes down about 3′ for every 5′ square. There are torches sunk into the walls every 30′ of the 120 foot tunnel.
The walls are old, but have held up exceptionally well over the years. The whole place smells earthy and musty. It is obvious no one has passed through here in many years.
Room 1-1: At the end of the long tunnel are 6 alcoves, 3 on each side of the wall with what at first may appear to be dirty old bronze or iron statues. Closer inspection reveals they are actually zombies that activate and attack!
6 Zombies: Init -4; Atk bite +3 melee (1d4); AC 9; HD 3d6; MV
20’; Act 1d20; SP un-dead; SV Fort +4, Ref -4, Will +2; AL C.
After the battle, the party will see two huge iron banded thick wooden doors. Both are locked. In front of the door are the corpses of what appear to be two dead adventurers. The bodies are very old, perhaps a century or more. There is little more than scraps of cloth and bones. Closer inspection will indicate the doors were closed by the adventurers before they succumbed to their wounds.
Loot: Rummaging through the deceased adventurers will yield a Silver Dagger, a pristine set of Thieves Tools, a scroll with the Level 1 Spell- Ropework, a solid staff, a Level 2 Enchanter’s (Neutral Wizard) spellbook with 7 First Level Spells, and a journal with entries regarding the Wolf Lord. (See Bevin’s Journal.)
The two large stone doors are locked. The lock is centered between the two doors. A large bronze carving of a wolf’s head is above each door. The lock is DC 15 with a Poison Needle trap within that triggers when the lock is opened with anything other than the proper key. Trap DC 15 to detect/disarm. The poison is the equivalent of Asp Poison Fort Save DC 20 1d3 Agi/1d6 Agi. Normal healing.
Once the doors are opened… To be continued.
