VBWyrde is the alias for the programmer who has primarily developed the Elthos RPG application, using visual basic and asp.net (as of 2014). The Web Application can be found at http://elthos.com. VBWyrde has been active on this project since 1994 when application development began. The rules system for the Elthos Prime system was created in 1978. The rules system for the Elthos "One Die System" (ODS) was created in 2006, and is an distillation and simplification of the original Elthos Prime Rules. Between 1994 and 2007 the visual basic application that vbwyrde created based on the Elthos Prime system was developed, tested, played with and then put on the shelf due to visual basic 6.0 being too difficult to support in the public domain. Starting in 2007 vbwyrde began work on The Mythos Machine, which is the web application version of the Gamemaster's Toolbox, and embodies most of the original application's features, leaving out only the mapping and combat system. Mythos Machine has been online and available for public use since 2009, and officially went into Live Production mode on Dec 21, 2018.
