Am I allowed to freely use content included in the D&amp;D SRD?
<p>Are there any restrictions on using content included under the <a href="http://media.wizards.com/2016/downloads/DND/SRD-OGL_V5.1.pdf" rel="nofollow noreferrer">D&amp;D System Reference Document</a>?</p>

<p>As a hypothetical, if I were writing a fantasy book, could I freely throw in a Yrthak or Gray Render with no restrictions?</p>

<p>I'm thinking of publishing a supplement for another RPG under their Open Game License that includes creatures in the D&amp;D SRD, which has all relevant information in its first pages.</p>

<p><strong>No you cannot</strong></p>

<p>The 4th paragraph identifies proper names (among other things) as “Product Identity” and subject to the restrictions in Clause 7 of the license which starts with:</p>

<blockquote>
  <ol start="7">
  <li>Use of Product Identity: You agree not to Use any Product Identity, including as an indication as to compatibility, except as expressly licensed in another, independent Agreement with the owner of each element of that Product Identity.</li>
  </ol>
</blockquote>

<p>Notwithstanding, Wizards of the Coast have only licensed what is <em>in</em> the SRD. If it is in some other book or on their website but not in the SRD, normal unlicensed copyright applies.</p>
