Welcome Challenge

You open your eyes in a place that feels both vast and enclosed, the air thrumming with unseen machinery. This is The Hub, the centre of all journeys. A great sphere hovers before you, etched with shifting glyphs, as if impatient for you to prove you belong here. The first gate is simple, almost insultingly so — but it watches how you step before it lets you walk.


Question:
