The Rune spell is a favourite of vicious, trickster sorcerers, who would place them upon doors, chests and other hidden corners. When anyone approaches the Rune, it would explode, causing tremendous damage. Recently, among the various trade towns, there have been mysterious explosions at the market-places, guild halls and home-steads. Among the rubble, there is always a fragment of stone, wood or even cloth inscribed with a sigil in the form of a stylized S.

1. Adventurers and tomb-robbers have just plundered a near-by tomb of an ancient Sorcerer-King, who has placed his Sigil upon his treasures. Unless those stolen artifacts are returned to his tomb within days, the Rune spell upon them will activate, causing untold harm and woe to the innocents (and the not-so-innocents).
2. Rivalry between various merchant guilds take a violent turn as one takes to hire a Sorcerer to use the Rune spell to disrupt the business of another rival. However, finding a Sorcerer who can use the Rune spell is not trivial and gold alone is hard to persuade him. What did the guild house used to hire him? What is the Sorcerer’s ultimate goal?
3. A doomsday cult is using those Rune spells to “fulfill” a prophecy which they have foretold long ago. Soon their preachers and persuaders would take to the streets, lamenting the lost, lashing out at the lords for their inability to stop the attacks and soon even predict a couple of attacks to gain followers. Their motive is unknown.

Editorial note: The Dragon Warriors world is one not yet accustomed to guilds. This scenario concept, developed for application across various RPG settings, refers to merchant guilds which might be more developed in the gameworld of other games but not canonical Dragon Warriors.
