Mod details
I would advise you to act fast as you can as soon as you enter your world, for they could be everywhere or nowhere. Get some wood and build a shelter immediately. The monsters on this earth have a weakness to silver, so you should go grab some.
Monsters are unpredictable and dangerous. You will need to get used to them. If you want to know of a common monster you may encounter first, that would be a wild ravager. Nobody knows where they came from, so people just assume they haven't been taken by Illagers yet.
I will tell you important things that could help you survive. There are soulfire sand patches found throughout the world. People believe these came from the "Demonsion", a dimension of soul energy. These patches make way for silver golems, but more importantly, soulfire blazes. Soulfire Blazes may have a soul or 2 on them. Be sure to kill them, for souls are a necessity here. 
For whatever reason, we have found a way to use souls to craft ancient forgers, the main being the Soul Table. This is the gateway for so many other things to craft that we never knew of.
We will need this for Soul Stone, something that will be needed for a portal. A portal that will lead us to the Demonsion. This dimension is rich with souls, but just beware of that temple in the distance...
And please, for whatever you do, just remember the rules of these portals: You need to build them in 3 by 3, be sure they are lined up along the path of the sun and use their igniter on the middle block.
Through documentation, we have found other portals and summonable creatures. The images of them lay below:
A wyvern egg is something you can get by killing a wyvern on the mountains and tearing open its corpse with a stone sword. If you're lucky, you can get an egg. You could either hatch and summon a baby wyvern you can tame with golden apples, or use it for what this recipe entails...
There are creatures we can make with Soul Wither Skulls and Fiery Pumpkins. Surround a wither skull with souls to get that Soul Wither Skull, or smelt a lit pumpkin to get a Fiery Pumpkin.
We have found fiery pumpkins can make obsidian golems.
The Soul Wither Skull was put in the middle of a wither formation and it brought upon a strong foe.
There are other formations the skull seemed to have a reaction to...
There are other dimensions that have portals with the same rules.
