Cîer'Citèlle

You focus on diverging paths of Cîer‘Citèlle conjuring a bidirectional two dimensional portal between Cîer‘Citèlle and the material plane.
The portal conjures after successfully concentrating for one minute. Any Creature on either Side of the portal can see towards the other side of the portal on the other plane, it can however not see anything on the same side on the other plane.

While opening portals at large energy focal points of 5 or more diverging paths is concidered to be rather safe, most mages consider it foolish to travel through smaller knots due to increasing risks of magical mishaps happening.

Cast at third level the portal opened has a width of ~0.5 Meters and a hight of ~1,8 Meters. It collapses after five minutes, or as soon as its caster ends it as an action.

There are a multitude of ways to find crossings suited to open a portal in the material plane: Most of the major intercections have been mapped out, but such a map is costly to copy due to the value of its information. As the crossings also represent points of magical prowess in the material plane some of them have been marked long ago by monuments such as stone circles or altars. The concentration of energy also enables a person to find crossings by casting detect magic.

Alltough traveling on the magical paths isnt instant, the distance traveled in a given time is far greater than in the material plane. Once a traveler has reached his destination he can leave though a persisiting portal kept active by the gatemages or cast a new portal.

”Ah, yes, spellspun gates. Portals, some call them. "Death-doors" is the term I prefer. The reason? Well, each step through one is a step closer to the time when your death is standing waiting for you on the other side—with a big cold grin on its face and a sword in its hand you'll have no time nor chance to avoid.”
