Getting close to the door will reveal a riddle, which is basically two very simple mathematics equations. In these equations, one variable is represented with a question mark (?), and the other variable is represented with two question marks (??) as shown in the picture below. The number at the center of the triangle is the sum of the numbers on the three corners of the triangle. Solve the equation to get the variables (? & ??).

**Top Equation**

11 + Magical Creature (2) + ? = 21

? = 8

**Bottom Equation**

Magical Creature (5) + Magical Creature (9) + ?? = 17

?? = 3

On the left side of the door, you will find a tablet with ‘?’ on it. Interact with the tablet and change the symbol to the magical creature corresponding to the number 8 as shown in the picture below.

From the door, turn around and climb two flights of stairs to reach the tablet with ‘??’ on it. Interact with the tablet and change the symbol to the magical creature corresponding to the number 3 as shown in the picture below. This will unlock the door. Go inside to open the chest and get clothing items.
