Stair Gate

These giants are crafty creatures, they must have realised that I was trying to get up to the upper level of their HQ to destroy their cunning secret devices.
A large, rather confusing barrier has been erected in my path, they call it "Stair Gate". My attempts had, so far, only got me to the first stair, but it was progress! Thwarted before any real headway could be made, thier secret devices must be incredibly important.

I've heard rumour of these devices tracing back to the ancient Egyptian heroes, but there may be a rather lengthy training video on the subject, I must continue my research!
