Gakiway
Gakiway is simply a modification to how planes is completed in The Underworld Speed Clear. It is more of an advanced tactic. It can be used within Terraway UW and other methods of UWSC.
Normally in UWSC when doing planes you can either semi-glitch or full glitch.
In Gakiway, the sole Banished Dream Rider at reaper spawn is not killed. Instead, a Gaki ally is spawned with a Mystical Summoning Stone to help the Reaper tank during the execution of The Four Horsemen quest.
First, the patrol at the Reaper area is spawned and you let it pass like usual. Next, the 3 Terrorweb Dryder (yellow)s and the Wailing Lords are killed which spawns the Reaper of the Chaos Plains. Note: the sole Banished Dream Rider is NOT killed. As soon as the reaper is spawned, you instantly take The Four Horsemen quest. There is a like 1 second time-frame from the moment the reaper is spawned that you can take the quest. He is spawned in aggro range of the sole Banished Dream Rider and will start attacking it after this 1 second time-frame. You will be unable to take quest and interact with reaper when he is in combat, unless of course you use GWToolbox++. Next, you want to attack (not kill), the sole Banished Dream Rider and pop a Mystical Summoning Stone. I believe its best to pop it in between the reaper and Dream Rider, not sure. Then go on to complete The Four Horsemen quest as usual. The reaper + gaki will tank and slowly kill the sole Banished Dream Rider for the time being.
Around the time pool's side is done by the Ranger/Assassin, the Gaki and Reaper may have killed the sole Banished Dream Rider. If not, the T4 kills the sole Banished Dream Rider after he/she is done with pits side. T4 should be careful not to kill it TOO early. This is because then T4 will have to juggle the Mindblade Spectres that spawn on pits side while waiting for T3 to kill his 2 Horsemen. So communicate. The reaper should be now be out of combat. The quest will not update, and therefore the Reaper is not safe, until the Reaper is out of combat. That is, until the sole Banished Dream Rider is dead, and no other aggro is on the reaper.

Here is a video example, skip to 5:40. Note: this run was not the standard Terraway, but still should give you an idea of Gakiway. The patrol spawned at Plains reaper was glitched by their T5. See http://gwscr.fbgmguild.com/viewtopic.php?f=31&t=1877 for their full run.
