Burn a way out.

The guards didn't seem in any hurry and probably intended to leave you there for a while. You'd like to eat something but it was unlikely that you would be fed before nightfall.

The cell is bare of anything useful, except for a bucket on a corner but you would like to be gone before the need to use it presented itself.

You tried your powers but the small amount that got back indicated that you truly overused them today. In the past it would have taken a good night of sleep or the use of a potion or trinket to recharge your powers but all your stuff was in the hands of your mistress after she magic lyrics stripped you and you had no time or envy to sleep on the lice infested straw in which you saw some rats playing.

Your only shot was something your brother taught you. As he studied a lot and used most powers he had each day in experiments and crafting, he always was on the lookout for ways to recharge his powers.

While all mages use the magic that imbues the world, lighting it with their inner spark of energy there are other ways to gain powers. Demonic deals, blood rituals, pacts with deities and soul draining were the most effective but either unlikely to be used or rather frowned upon. He discovered an elven technique of meditation that tapped into the Ley lines that cross the earth to regain power.

To be honest you never did it, or saw it done. Your brother showed you how to do it and you rembered the correct runes to do it, but you obviously didn't try it with him, he told you that it worked and that he did it when he had a lot of work to do.

The ritual if done correctly would allow you to regain your fill of power and feel as if you had just a full 12 hours of sleep I little less of an hour of meditation.

You never were sure if it was real or if it was a joke on his part given what he described to you. You had to sit cross-legged in a circle of seven runes, totally naked and masturbate while focusing on the Ley lines around you.

It was in line with what you knew of elves and their lack of modesty but you'll only know by trying.

A bit of coal let you trace the runes on some of the cobblestones and after checking that no guard was there you stripped before sitting, facing away from the door.

Already you felt that the circle had an effect. Once you put a finger or two in your pussy and played with your clit with your other hand you truly felt one with the universe. Forgotten was the dirty cell or all your troubles, you were lost in an infinite void between large streams of colorful energy.

As you were getting more excited and finally orgasmed more than once, huge explosions like new stars erupted, each time the shock from it cause a small tendrils of one of the large streams to drift your way until they anchored themselves into your soul.

Drenched in sweat and sitting in a puddle of your intimate juices you open your eyes, a quick use of a clock spell tells you two things. You have enough energy to cast it and a lit to spare do the spell worked, in addition to that it only took one hour, one hour of a continuous orgasm and of communing with the universe.

The ritual being over you put back the clothes you borrowed from the thief, you could use an illusion to get other clothes but there was no need to waste power until it became useful.

The door was too dangerous of an option, there were a lot of guards in the precinct. You launched the rope around a bar of the window that let air and light on the ceiling of your cell. Rope climbing was something you had a lot of practice in, after years of sneaking in or out of your room.

Like you expected the bars were simple cheap iron, a bit rusted and without any magical protection. The guards didn't see you use magic or they might have put you in a special cell. Pyromancy was you second gift in the magical arts, you were able to learn spells from other domains but fire and illusions were instinctive and natural for you. With your power reserves to their max you quickly melted away all the bars except the one your rope was tied to.

You slipped through the hole and took back the rope. You are in a wall enclosed yard at the back of the precinct. Before anyone could notice you, you cast an illusion to make you look like a guard in armor.

You easily spotted a door that led out and as someone was getting out you followed him through.

A few turn through the crowded streets you get in cover and change the illusion for an outfit more in tune with your style than the flashy clothes you took from the thief but the tampering your mistress did on your powers concerning clothes was still effective and your dress ended more revealing that you'd have liked.

Now you could either hunt for the thief to get vengeance and your gold back, go back to the tower or try to find Nancy.
