Lachlan Adamson, also known as Quickdraw, and his twin brother Julius are mathematical geniuses, and together they are sometimes known as the Cowboys.
In 1989, both Lachlan and Julius studied under Max "Wizard" Epper at Trinity College in Dublin, where they also met Jack West Jr. and Zoe Kissane. They majored in Cosmological studies, and did some study in ancient history.
In 2002, the twins went on a backpacking trip to Easter Island with two American anthropology students. Lachlan hooked up with one of them, Stacy Baker, despite Julius having a crush on Stacy.
Before The Six Sacred StonesEdit
While searching for the Spring of the Black Poplar, Julius recalled the twin's trip to Easter Island, and learned that Lachlan had slept with Stacy Baker, and was furious at Lachlan.
Along with their colleague, the oceanographer David Black, Lachlan and Julius discovered an ancient gateway in the Mariana Trench. Because there were Thoth symbols engraved on it, they invited Jack and Zoe to take a look, but only Zoe joined them.
Born in Scotland, the twins both have typically carrot-red hair and freckled faces. Once some of Wizard's students at Trinity College, the twins proved themselves to be brilliant in the fields of mathematics, cosmology and anthropology, which makes them just as valuable to the team as anyone else.
