The Waste Storage Facility

Qistrel

So, found the secret path to the facility from the Highway, gave the janitor enough essence to clear the chute, which opened an entrance into a small area that is basically an administration block. Commander n'Rotri tells me to bring her brains from the vaults, and when I say I am the needed reinforcements, she tells me some stuff I need to do in the vaults to stop the zombies breaking out, including finding some cogs that are down there and fixing a control panel.

But I can't for the life of me work out how to get into these vaults. Can't find secret exits, can't find any things to pull/touch/open except for the machine that gives me a h/m/e blessing when I touch it. There's just these 5 rooms.

I'm sure I'm missing something obvious. I fail at Lusternia again. Help anyone?

There is a desk you can push. It will reveal no "exits", but it will reveal a sewer grate.

Thanks!
