+	</div>
+	<p>
+		I wanted to implement this system in my game "The Labyrinth II" ever since I was maybe 13, but the project failed a few times and for the last few years it has been just rotting in the back of my mind. Well, I have decided to return to it again.
+	</p>
+	<p>
+		The system is inspired by the spell casting system in the videogame <a href="https://en.wikipedia.org/wiki/Dungeon_Master_(video_game)">Dungeon Master</a>. I really liked the way you had to actually study the spells and then cast them. This was not selecting a option in a menu, it was way more involved - and exciting. Originally, when I was thinking about the spell system I wanted in my game I just wanted to pretty much copy their system, but at some point, this appeared to me as a better idea. I think it will allow you to feel not like you are uttering the spells, but insted like you are casting them with your wand, or finger, or a screwdiver or whatever. Plus it gives you a nice natural way to upgrade it once you do get a better mana-channeler: just increase the dimension of the matrix! Allows you to cast new, more complicated spells, and does so in a natural way only once you've mastered the simpler spell matrix.
+	</p>
+	<p>
+		Now, I have to admit, that I am not at all sure if this system will actually work in a modern game, or, really any game that's not basically turn-based. I do have some ideas how to solve these problems (including a time slow-down mechanic), but that is too far in the future now. I am planning on taking this very easy and slow, more focused on having fun and exploring the godot engine, rather than trying to sprint to the goal of a finished game.

+				<p>
+					A log from the spellbook, it detects all entered paths. It also has a dictionary of paths and spells, if you enter a path that corresponds to a spell, you cast it!
+				</p>

+				<p>
+					This is how I can interact with the spellbook from the editor. I can add in nodes (it then works with them automagically, so I am not anyhow limited to the 3x3 grid). And I can also add in the spell paths and names (I can then use these to emit a spell_cast event with its name, or something like that).
+				</p>
+			</div>

+	</div>

+	<p>
+		Once I tried actually using it in a control node, I found out the mapping of the mouse was completely off, I remade it into control nodes, which I am actually happy about as I feel like the nodes being buttons makes more sense than them being sprites with a collision box that only reacts to the mouse, or whatever I was using, I don't wven remember, but it was wacky :D. But I encountered a problem! I still had to use the Line2D, which is a Node2D. And it's position just did not map well. Through experimentation I found out that it was using the position as relating to its scene origin, but once the control scene was inserted into a control container, it got scaled, as controls should, but it was now offset and the line was not. The only solution I could find was putting the SpellBook scene inside of a MarginContainer, and offseting it using margins and thus preserving its 'relative origin', instead of letting it stretch. I do not like this solution as it requires manual fiddling if you want to change up the HUD, but it was the only solution I could find.
+	</p>
+	<p>
+		Here is a bit of code, so that I can test my code block css:
+	</p>
+	<code>
+## Add a node to current spell
+func _on_spellnode_entered(node: SpellNode)-&gt;void:
+	if is_receiving_spell &amp;&amp; not spell_builder.has(node):
+	# Append node to the spell builder
+	spell_builder.append(node);
+		# Add new point to the spell line and set the old top to the new nodes position
+		spell_line.add_point(node.position)
+		spell_line.set_point_position(spell_line.get_point_count() - 2, node.position)
+	</code>
+	<p>
+		I would like to add some kind of syntax highlighting, but from my research I'd have to write a php function for that, as css cannot look for key words, and writing a bunch of php is not something I am currently in the mood for, so this will have to do, for now.
