Sue Medley's Yserbius Walkthrough

Sue Medley published a thorough walkthrough for Shadow of Yserbius in SynTax in 1995. This walkthrough details every map and nearly every NPC interaction, along with Sue's pithy commentary. It is an essential reference for the Yserbius completionist. Sue is a dedicated player of the game, and I am thankful for her time in compiling this information.

Tiger's Yserbius Item and Quest Walkthrough

Tiger wrote this straightforward guide to collecting every quest item and completing every quest in the deeper reaches of the Volcano. It is the most simple guide to completing the game. Tiger is an outstanding member of the Yserbius diaspora, and his story about a group of adventurers (inspired by friends from Yserbius) was recently published! You can read more about his work at TigerForce.net.

Twinion Help


Fates of Twinion Walkthrough by Ragnar/Nigel

This is Ragnar's update to Nigel's classic Fates of Twinion Walkthrough. With the launch of the INNRevival server, and now the MedievaLands and INNBarn projects, Ragnar was inspired to complete a revised and improved walkthrough. He hopes this will be useful and help spark interest in the Fates of Twinion!

Frequently Asked Questions

Is this a complete remake of Yserbius and Twinion?

MedievaLands is a modern reimplementation of the original Yserbius and Twinion games on The ImagiNation Network. It does not use any of the original files. However, it does use data, textures, and map scripts which were extracted from the single player versions of these games. All code is 100% written from scratch, except for the map scripts, which were transpiled from x86 assembly to c#.

Many changes to the original game have been added. Some of the map scripts (the parapets, seasons quest, and keyhole lava bridge in particular) were completely rewritten to clarify their functionality for returning players. There are many more social features, and the chat and Tavern functions have been modernized. There is a brand new Bulletin Board and Guild system. The UI has been updated, since we have much more processing power to render more complicated GUIs. I am currently working on a complete replacement of almost all the items from the original games. Stay tuned!

Can I donate money to keep the server up?

No. I do not accept donations - but please send me a note to hello@medievalands.com telling me how much you enjoy playing - this is so appreciated!

Can I import my characters from INN or single player Yserbius?

No. To make sure no cheat characters can be imported, as well as to allow for new features, I do not allow people to import characters from the original game.

Can I run MedievaLands in single player mode? Can I run my own MedievaLands server?

No. MedievaLands is online only, and there is only one MedievaLands server. I hope you will invite all your friends to join us!
