The River Salve marks the border between Misthalin and Morytania. Completion of the Priest in Peril quest is required to gain access to the Morytania side of the river. There is a Fairy ring on the one island in the river, accessible with code BIP.
The River Salve is a barrier between Misthalin and Morytania. According to legend, the river will not allow any evil of Morytania to cross the banks. The river was blessed by the Seven Priestly Warriors in the year 1200 of the Fourth Age, and the power of Saradomin keeps any creatures of Zamorak from crossing. This, however, has somehow been broken, as discovered in the Darkness of Hallowvale quest. During the Priest in Peril quest, rune essence is used to absorb the impurity of the river, caused by the Monks of Zamorak that came to Paterdomus and captured Drezel. Count Victor Draynor Drakan, brother of Lord Drakan, was an active participant in the Misthalin - Morytania War but, while fighting in Silvarea, was denied re-entry by Drakan, leaving him weak and stranded beyond the Salve.
Despite its immense power, various entities from Morytania have managed to cross the Salve at various points in time. Evidently this number has been sizable enough to prompt some humans to become vampire slayers, such as Dr. Randulf Harlow. Many vampires were trapped beyond the Salve after its initial blessing, forcing them into a hiding that, for some, may continue to this day. In the Year 164, a young werewolf named Gar'rth hoping to escape his race's violent lifestyle managed to cross the Salve, and was pursued shortly after by his uncle Jerrod. Drakan managed to visit Jerrod in a non-corpeal form during his time beyond the Salve, although he did not physcially cross. The werewolf Shanty Claws managed to escape Morytania by unknown means, although he, like many other escapees, forsaken violence. A "Mystery Figure" representing the werewolf race currently resides in the Champion's Challenge dungeon beneath Varrock, apparently without conflict. Recently, a vampyre known only as a "Sinister Stranger" has been sighted in Hemenster, although he also seems to have suppressed his race's inherent violence. Gus, a non-violent ghoul with above-average brain function for his race, is known to cross the Salve regularly in his work for Numinous Witchery Supplies Ltd. More significantly, though, a number of violent werewolves have recently been sighted near Paterdomus, where they have regularly abducted travellers in an effort to appease Lord Drakan's Blood Tithes.
While Salve is the Latin word for "hello", it can be more directly translated to "be safe", as salvere is the verb "to be safe". Therefore, this River is the "safe" river, protecting the rest of the world from the dangers of Morytania. It could be a reference that it is a welcoming site to refugees escaping Morytania.
