wait I never told you guys the ending... so it was some years later (and by some years I mean we were playing 3.5) and the player who had flipped the paper over had come back to gaming after a hiatus (married then twins) and was making fun of the .5 when he remembered the old game and ask the DM of that game (now playing in this game) "What in the heck is a 4 sided triangle" and without missing a beat, saying it like it was obvious "It meant it was behind the big waterfall on the map." we were so dumbfouned no one knew what to say... even WITH the answer we couldn't make that logic workoh wait the waterfall... a DM had this riddle to lead to (his entire planed campaign) a lost elven homeland... but no PC could figure it out. "The land and sea move as one at the four sided triangle" (i may be missremembering a bit of that it was 1997) we drew triangles we looked at the maps he drew... we begged for a clue. One player drew a triangle wrote 1 2 and 3 on the sides and said "The other side of the paper?" that campaign never started. We made characters did the first little get''ing the adventures togather' thing and then stalled.
