Don't know much about the Zelda world, but need a basic guide?
Well, I've taken the time to make one for you..
Hyrule is a basic world made up of thirteen places, listed:
• Gerudo's Fortess
• Gerudo's Dessert
• Lake Hylia
• Lon Lon Ranch
• Hyrule Castle
• Castle Town Market
• Kakariko Village
• Goron City/ Death Mountain
• Zora's Domain
• Zora's River
• Lost Woods
• Kokiri's Forest
• Deku's Tree
Like every world, Hyrule is made up of three races, all with cultures of their own.
Zoras primarily reside in the Zora's Domain, while some may appear in Lake Hylia. They can exist both in and out of water, but they are best adapted to life in the water. The Zora race is known for their light blue skin and fins coming from their forearms and legs. The only known weakness for a Zora is heated places and fire. Zoras shown no particular culture other then a simple rule under a King or Queen of their time.
Also, in order to marry in the royal line you must give the Zora Sapphire to the one you intend to marry. A long time ago, Princess/Sage Ruto gave the Zora Sapphire to Link as a gift for rescuing her and as an engagement ring.
Gorons live in Goron City on top of Death Mountain. Their major source of food is rocks from Dodongo's Cavern. Gorons are known for their rock-like appearence and odd sounds when communicating. They have a weakness when it comes to any body of water deeper than a foot, they sink like rocks. Gorons have a simplistic tribe-like culture, ruled by the domesticated king for their time.
The Goron Ruby is the Goron Tribe's treasure, they hold it symbolic and display it freely in their city for all to see.
Dekus had leaves on their heads, red glowing eyes, and short, wide, mouthes that are hollow tubes which can't shut tight, preventing them from being able to swim without drowning. They could shoot nuts out of their mouths, similarly to how Octoroks shot rocks. Dekus had bark rather than skin, and were possibly made entirely out of wood; they perished quickly if set on fire. Deku Scrubs typically lived inside Deku Flowers, and sprang out of their flowers momentarily to attack any intruder. Upon initial damage, Dekus popped out of their grounded, floral homes. Dirived from Dekus are Kokiri which are small children who live under the Rule of a giant Deku Tree.
The Kokiri Emerald is held by the Great Deku tree, though most of the children have no clue as to what it really is, Dekus are symbolized for it.
There ye go. <3
