Alfheim is an add-on to Botania, allowing you to build a portal to Alfheim - one of the nine worlds of Scandinavian mythology, populated by light alvs, otherwise known as elves. There you can find all the materials that otherwise can only be obtained through a special trading gate. Explore the world, learn the story of Alfheim and discover the secret elven technology of mana-infusion. Everything you need to know about this add-on you can find in your Lexicon - in-game manual from Botania.
Also you can become an elf! Just use Elven Story Mode mod. Your new target is to survive in Alfheim, build up portal and get back to Overworld! And at last and the best - you can fly on pretty looking wings of one of nine available races!
