You must be thinking of something different here. Sil'dih was the sister neighbor of Ul'dah. It created a way of flood control which resulted in a war between it and Ul'dah over water, which Ul'dah ultimately won due to their thaumaturges creating a powder that brought the dead back to life as zombies, which they used on Sil'dih via catapults tossing it into the city. They then lied to the populace of Ul'dah that Sil'dih had been bringing back the dead, and used it as a preface for war, and then sealed Sil'dih so everybody would die.
