+1. **Table: Items**
+   - This table will store information about base items like powerups.
+
+   ```sql
+   CREATE TABLE items (
+       item_id serial PRIMARY KEY,
+       name VARCHAR(255) NOT NULL
+   );
+   ```
+
+2. **Table: Synonyms**
+   - This table will store synonyms for each item, referencing the `items` table.
+
+   ```sql
+   CREATE TABLE synonyms (
+       synonym_id serial PRIMARY KEY,
+       item_id INT REFERENCES items(item_id),
+       synonym VARCHAR(255) NOT NULL
+   );
+   ```
+
+3. **Table: Genres**
+   - This table will store different genres, like "fantasy" or "modern day."
+
+   ```sql
+   CREATE TABLE genres (
+       genre_id serial PRIMARY KEY,
+       name VARCHAR(255) NOT NULL
+   );
+   ```
+
+4. **Table: Items_Genres**
+   - This table will establish a many-to-many relationship between items and genres, as an item can belong to multiple genres.
+
+   ```sql
+   CREATE TABLE items_genres (
+       item_id INT REFERENCES items(item_id),
+       genre_id INT REFERENCES genres(genre_id),
+       PRIMARY KEY (item_id, genre_id)
+   );
+   ```
+
+With this schema, you can:
+
+- Add base items like powerups to the `items` table.
+- Associate synonyms for each base item in the `synonyms` table, referencing the corresponding item.
+- Categorize base items into different genres in the `genres` table.
+- Establish relationships between base items and genres in the `items_genres` table.
+
+Here's an example of how you might use this schema:
+
+```sql
+-- Insert a base item
+INSERT INTO items (name) VALUES ('Health Potion');
+-- Insert synonyms for the base item
+INSERT INTO synonyms (item_id, synonym) VALUES (1, 'Health Potion');
+INSERT INTO synonyms (item_id, synonym) VALUES (1, 'Stimpack');
+-- Insert genres
+INSERT INTO genres (name) VALUES ('Fantasy');
+INSERT INTO genres (name) VALUES ('Modern Day');
+-- Associate the base item with genres
+INSERT INTO items_genres (item_id, genre_id) VALUES (1, 1); -- Health Potion belongs to Fantasy
+INSERT INTO items_genres (item_id, genre_id) VALUES (1, 2); -- Health Potion also belongs to Modern Day
+-- Select the Fantasy name of an the heavy armor base item that you are looking for.
+SELECT genres.name
+FROM genres
+JOIN items_genres ON genres.genre_id = items_genres.genre_id
+JOIN base_items ON items_genres.base_item_id = base_items.item_id
+WHERE base_items.name = 'heavy armor'
+  AND genres.name = 'Fantasy';
+```
