Torn Net

Hey there! I'm Kazimir, the Portal Keeper. When the stone monsters attacked, all spatial magic collapsed at once. Thought connection doesn't work, the Portals are messed up. We had to send messenger pigeons to the Iron City! Can you believe that?
I suppose we can solve the problem if we find a sustainable source of power. Where do we get it? Oh, I know!
Last year elves installed their streetlamps in the city. They said, they would work forever, because they charge from magic crystals. If I had those crystals, I could fix the Portals in no time. But who in their sober senses would dare to go to the city?

I wish we had a mana-station...

Just what I need. Let's try it...
Look, it works! I don't think it will sustain an army, but for sporadic single travels it will work just fine.
