Starwolf (novel series)

[3] While in intersteallar space Morgan Chane survives a deadly chase by his ex-fellow robbers from Varnan, Starwolves, one of which he killed in a self-defence.

On his escape he gets captured by an experienced starship captain, Dilullo from Earth who is leading a group of Mercs (mercenaries) with a mission to a planet called Kharal.

Captain saves him, but quickly learns that he is one of Starwolves, well known robbers who raided almost entire galaxy and whom it's usual to kill on spot.

As usual for Mercs, the mission promised to be dangerous so in exchange for his help Captain offered to keep origin of Morgan Chane secret.

By tracing cruiser's path, they reach nebulae's planet where super weapons were expected to be found, but find only enormous intergalactic spaceship wreckage.

Mercs captured vhol-lans scientists present at the ship who explained that there was no super weapons and this ship belonged to an ancient powerful alien race called Krii, who accidentally landed on the planet, but survived in stasis for many years and were awaiting their rescuing fellows Krii-s who were expected to appear soon.

The latter are notable for being so dangerous and so mysterious that even starwolves do not dare to step their foot on - they have laws that bar them from landing on Arkuu, the planet of the Closed World, where natives do not wellcome anyone.

The Mercs find Randall, who has re-discovered what the Closed Worlds were trying to hide, an astral projection machine for the mind that allowed the user to wander the universe as long as the body was taken care of.
