### 216

Using your index finger you inscribe the symbols in the malleable surface of the blank square. At first nothing happens. Then your inscription begins to fade until it has vanished completely. You step back, but not quickly enough to avoid a massive charge of electrical energy, which leaps from a tiny hole above the door and stabs you in the chest: lose 10 ENDURANCE points.

If you survive this grievous wounding, turn back to 25 and study the remaining symbols very carefully before you attempt to open the door again.
