Description of Sacred Dragons
As mentioned, there are a total of 10 dragons in the game, 9 of which you will have to kill, and one you will work for.
Ssilif, Marsh Dragon:
This creature resides to the northwest of Draken, with the nearest portal located at Mistdale Castle, and slightly further, there's a portal from the Jurg-Nar Valley. Besides various junk, this dragon always drops a portal rune. The portal activated by this rune is located west of where our scaled friend resides. It is quite possible that you may encounter difficulties finding the portal, so look for a tree surrounded by light; around it, there will be ghosts, and nearby is the portal. Near this dragon, you will encounter Cave Fish, Tarantulas, and Poison Trolls...
Sislif, Keeper of Frostgard:
You could say you meet him through the storyline, although you can get the first Ancarian element without fighting him. The dragon is located north of the Ice-Creek Valley, or more precisely - right in Frostgard, which is southwest of where you found the element. The rune you find in the dragon's corpse activates a portal hidden behind a chunk of ice behind the dragon, so there should be no problem finding it. The portal will take you to Wyvern Pass. Near this dragon, you will encounter Frost Giants, Ice Lizards, and Ghosts...
Sirifkam, Fire-Breathing Dragon:
You will definitely encounter this dragon, as he is on the storyline path and will make a pathetic attempt to stop you from acquiring another element of Ancarian. The dragon will drop a rune - the portal it opens is near the pedestal of the fire element and leads you to Brayrock. Around this dragon, you will find mages and Dragonian Giants...
Di'Key, Orc Lady:
Another storyline dragon... Along with a bunch of skeletons, she is stomping near the entrance to Horad-Nur. You will be invited to fight her to gain permission to enter the city. Killing the dragon, rather than the orc guard, is worth it for prestige. I recommend luring the skeletons and orcs out first, and then engaging the dragon itself.
Lorinar, Tir-Fasul Fire-Breather:
This fire-breathing dragon is quite easy to find... At first glance, it seems you can reach him from Tyr-Fasul or Mascarell, but that is not the case. The only way to him is through Porto Draco. Exit the town to the northwest and walk along the river; you will see a small forest path that will lead you to the dragon. Near this dragon, you will find Dark Elves, Ghosts, Forest Trolls, and Lizards...
Draconis Mortis:
This fire-breathing dragon is located on an island, and the way there is through a portal. To get there, go to Crows Rock Castle, near the stables. North of the stables, you will see gates leading into a cave; go inside. By examining the central branch of corridors, you will enter a room with a large number of enemies. Defeat them, and one of the mages will open a portal leading to the island to escape; however, something will go wrong, and he will perish from his spell. Walk through the portal, and you will see the dragon to the east of you. Around the dragon, you will see Goblins, Thieves, Ronins, Wargs, and Bandits... A very useful place for gaining experience at the start of the game.
Relerisif, Marsh Dragon:
This fire-breathing dragon is quite difficult to find; he is located on the third level of Jurg-Nar (he is also the second level of the gnome catacombs, and it is on this level that the lever draining water from Verag-Nar is located), but I strongly recommend finding and fighting him because, as with any dragon, he gives a lot of experience and may drop good items. Near this dragon, you will find Water Gargoyles and Ghosts...
Lormir, Defender of Honor:
The only friendly dragon resides in the village of Drakenden, near the town's trader. He will give you several interesting quests that are advisable to complete (or do you not need money and experience)...
Winters Rigor & Frosted Death:
These two dragons were added in patch 1.8. (Sacred PLUS) They are located in the new area of the plains of Tir-Haddar. During the completion of the storyline quest (not far from the Main Settlement of the Elves), these two ice dragons guard the last ice elf priestess.
