The Tower of the Mammoth

Publisher's blurb:

The Tower of the Mammoth is of strange hue,
they say it was erected in one night as new.
From out of the ground it came,
as witnesses stood in awe and pain;
for none dare voice an objection;
Lest they generate a connection
to whatever dark entity resided within.

~ The Tower of the Mammoth, by the Mad Bard.
527 C Æ (High Summer Waning).

The Tower of the Mammoth is a mid level adventure based on Robert E. Howard's short story by a similar name. It is suitable for 3-6 characters of levels 4-8, preferably a mixture of fighters and thieves, although a few magicians could be useful.
