Magical Space Vortexes

The Sun at the center of the epic system is constantly putting out droves of magical energy. This energy makes teleporting trough space to various planets impossible as it twists and warps the spell setting you off course on the way over. This has resulted in the death of multiple S.H.I.E.L.A. agents in an attempt to over come this effect. Thus far only the STALWART's power core can put off enough energy to shield the city and allow transport between planets at the cost of a colossal amount of energy.   Thus any basic teleportation spell is NOT allowed for travel between planets. Traveling to another plane is still possible and is common on Hyboria on other civilized planets however there is still a similar issue when traveling back to the material plane to a different planet. These magic vortexes will still release a large amount of energy into the spell as the targets come back, as though passing through space even though they have circumvented it.   Planar traveling spell will land you on target about 50% of the time with some serious magical side effects similar to that of a wild magic sorcerer. This uncontrollable magic has yet to be mitigated, thus planar travel is strictly prohibited except in the most dire of circumstances between planets.   The other 50% of the time lands you in the deep of space where you die, alone, cold, choking, and silent.
