In a Locked Room Wiki

Gerald[2] Angelo "Jelo" Bartholomew Edmarkson[3] is the founder and one of the leaders of the Locked Room Gang, a group of heroes who stop villains from taking over the multiverse, especially Galaximus.

Gerald is usually considered one of the mascots of the IaLR series. He is roleplayed by JeloJellyJam.


Pre-Locked Rooms

Jelo was born in Echo Creek, Los Angeles on Dec. 19, 1993. When he was at kindergarten, he met Rosewell, and they became friends. They entered the same high school and college. When he was 12 he joined a camp named Camp Sherlock. At one time, he went up the camp bus and looked at the Comet Observatory with a telescope, but quickly went back inside due to a traffic sign about to hit him.

Entering the Rooms

One faithful day when he was 23, Jelo and his friends were camping at a nearby forest. While Jelo was stuffing his face with a ton of marshmallows much to the confusion and chagrin of Rosewell, Peter told everyone a campfire story.

The story was about the legend of a huge set of different universes called "Locked Rooms" and the entrance to it, said to be hidden there for hundreds of years.

Jelo said, "That's crazy! A entrance leading to different universes?" Just when everyone didn't expect it, a Wizard Zombie jumped out of nowhere and started shooting spells at Jelo and his friends. Jelo then ran around like crazy, and was hit by the zombie's spell. The portal then suddenly activated when Jelo neared, and sucked Jelo in.

Rosewell, worried about Jelo, rushed to the entrance, but it closed. Meanwhile, Gerry called the authorities about Jelo accidentally entering the rooms, but nobody believed him because they still think it's a mere legend. Gerry decided to go and research more on the Rooms' entrance in hopes of opening the entrance and saving his friend. Peter stared in shock, finding out that what he once thought as nothing but a fictional legend was actually real.

Post-Locked Rooms

After the gang escapes the Locked Rooms for the last time, Jelo was worrisome about the friends and family of "the missing ones". He decides to brush it off and enjoy the town celebration, but he felt really guilty, thinking about how would they react once they find out their loved ones ended up missing. He still stayed optimistic, however.

After a bunch of apologies, Jelo returns to his normal, suburban lifestyle. He still hangs out with the Gang, though.


In his first appearance in the Hot Room, he was the letters "Jelo" in an orange background, a result of a curse. Some time later in the Cold Room, Jelo became a Papa Louie-style person. He then became a cartoonish-style person. He has messy hair, a brown jacket, brown shoes, a brown belt, blue pants and a light blue shirt. In his Flipline look, he had an aqua and black shirt, which he still keeps.

His current look now brings back his glasses. He now has brown sneakers, his pants now have more pockets and added seams, and he now wears a light blue polo shirt with a pocket. His watch was removed.


Jelo cares to help his friends through rooms. He is intelligent, usually easy going, witty, courageous and calm. He never gives up when doing a hard task, and likes to help other people around him.

Jelo is friendly to people. He is supportive of others, is organized, and likes studying. He also likes hanging out with friends, and also likes playing games. He also likes watching videos, and listening to music, usually those from the 70s-90s. Jelo can sometimes be a bit scatterbrained and clueless, however.

Like all characters, Jelo also knows how to break the 4th wall.


Despite being an ordinary human, Gerald makes up for it in his leadership skills and his swordfighting skills.

Gerald's weapon of choice is his trusty sword. Having learned fencing and swordfighting at the age of 20, Gerald could be considered good at it by now.
